Abstract
An insoluble material for adsorbing a pyrogen comprising a polymer of an aziridine compound. According to the present invention, a large amount of the pyrogen can be easily removed from a solution containing pyrogen, and a large amount of the material for adsporbing the pyrogen can be prepared in easy steps. Therefore, the adsorbing material can greatly contribute to the preparation of medicines.
